Embodiment 1

[0011] A production method of selenium-enriched agricultural products is used for the production of selenium-enriched apples. After 2 weeks of apple withering, the young fruit expansion stage (before bagging) and the first 30 days of apple harvest (after the apples are removed from the bag) by weight 1: Mix and dissolve the selenium-rich fertilizer with water at a ratio of 500 and spray it on the leaves. The amount of selenium-rich fertilizer per mu is 1kg / time, and the number of fertilization times is 2 times. Selenium-enriched fertilizer is in the form of solid powder, containing 0.3% sodium selenite, compounded with nitrogen, phosphorus, potassium ≥ 55%, calcium, boron, copper, zinc, manganese, molybdenum and absorption promoters, etc. 5.0-6.0% .

Embodiment 2

[0013] A production method of selenium-enriched agricultural products is used for the production of selenium-enriched chestnuts. When the female flowers are open and the young fruit is expanding, the selenium-enriched fertilizer is mixed and dissolved with water at a weight ratio of 1:500, and then sprayed on the leaves, and the amount applied per mu The amount of selenium-enriched fertilizer is 1kg / time, and the frequency of fertilization is 2 times. Selenium-enriched fertilizer is solid powder, containing 0.6% sodium selenite, compound with nitrogen, phosphorus, potassium ≥ 55%, calcium, boron, copper, zinc, manganese, molybdenum and absorption promoters, etc. 5.0-6.0% .

Embodiment 3

[0015] A production method of selenium-enriched agricultural products is used for the production of selenium-enriched cherries. Five days after the flowering of the large cherries and 15 days before harvesting, the selenium-enriched fertilizer and water are mixed and dissolved in a weight ratio of 1:500, and then applied to the leaves. Surface spraying, the amount of selenium-enriched fertilizer per mu is 1kg / time, and the frequency of fertilization is 2 times. Selenium-enriched fertilizer is in the form of solid powder, containing 0.3% sodium selenite, compounded with nitrogen, phosphorus, potassium ≥ 55%, calcium, boron, copper, zinc, manganese, molybdenum and absorption promoters, etc. 5.0-6.0% .

Abstract

The invention discloses a method for producing selenium rich agricultural product, which comprises following steps: spraying selenium rich solution onto plant leaves, diluting said selenium rich solution into solutions with different concentrations, then spraying it onto leaves, converting inorganic selenium into organic selenium by employing special technology in grain, vegetable and fruit, providing selenium for human body through food chain. The invention is characterized by simple and easy operation, high selenium availability ratio, low cost, selenium rich crop of 80-235 ug / kg.

Description

technical field [0001] The invention relates to a production method of agricultural products, in particular to a production method of agricultural products rich in trace element selenium. Background technique [0002] Selenium is called "the kindling of life", "sight protection god", "liver protection god" and "anti-cancer king" by the medical and nutritional circles. The absorption and utilization of selenium by animals and plants is very small, but the role it plays Selenium is very large, so scholars also call selenium "magic element" and "God of life", and it has been identified as one of the essential trace elements by the United Nations Health Organization. [0003] The human body is particularly susceptible to various diseases due to selenium deficiency. It is reported that there are more than 40 countries and regions that lack selenium in the world. The areas of selenium deficiency in my country account for 72% of the country's land area. Due to the selenium absorbed...
